TEMPEST — Emissions Security
TEMPEST Definition
TEMPEST Definition
TEMPEST, formerly known as emissions security, is protection resulting from all measures taken to deny unauthorized persons information of value that may be derived from:
- The interception of compromising emanations
- The analysis of compromising emanations
…from cryptographic equipment, information systems, and telecommunications systems.
TEMPEST Objective
TEMPEST Objective
The objective of TEMPEST is to deny access to:
- Classified information
- In some instances unclassified information
…that contains compromising emanations within an inspectable space.
Inspectable Space
Inspectable Space Definition
The inspectable space is considered the area in which it would be difficult for an adversary with specialized equipment to attempt to intercept compromising emanations without being detected.
TEMPEST Countermeasures
TEMPEST Countermeasures
TEMPEST countermeasures, implemented to reduce the risk of compromising emanations:
- Classified and unclassified equipment separation
- Shielding
- Grounding
